SPRING-orma.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed February 15, 1917. Serial `No. 148,761.

To all LU/Lola t may concor/n.'

Be it known that I, IVILLIAM I-IIRAM l'SnowN, a citizen of the UnitedStates 0f America, and a resident of Cleveland, county of Cuyahoga,State of Ohio, have invented certain new and useful Improvements inSpring-Oilers, of which the following is a full and clear specification.

This invention relates to that type of oilers employed on multi-ply leafsprings, and the object of the invention is to provide a siinple forniof device which be readily applied. to the spring and which willefficiently supply oil to the edges of the spring, whence the oil willbe worked into the spaces between the leaves by the independent slidingaction of the leaves upon each other in the well known manner.

In the drawingd Figure l is a side elevation of a portion of a springprovided with my device;

Eig. 2 is a perspective view of the device detached Eig. 3 is a verticallongitudinal sectional view; and

Fig. et is a vertical sectional view showing another way of applying thedevice to the spring.

The device consists of a clip preferably forme-d of sheet instal andembodying a top plate l and depending side plates 2, these latter platesbeing provided with inwardlyturned flanges 3 along their lower edgesadapted to engage under the lower side of the spring, the distancebetween the depending side plates 2 being `iust sufficient to receivethe spring between them.

The depending side plates 2 form, in connection with depending flanges tat the ends of the top plate, a chamber for holding a lubricating pad 5,which pad is adapted to absorb the lubricant and gradually feed it downto the opposite sides of the spring, the motion of the vehicle servingto agitate the pads sufficiently to bring about this gradual feed. Ahole 6 is forined in the pad and the top plate 1 is provided with anoil-hole 7 through which oil may be fed to said hole 6, which holeserves as a reservoir or retainer for the oil until it is absorbed bythe pad. The hole 7 may be closed by any suitable device, such, forinstance, as a rotatable plate 8 pivoted to the top face of the plate 1.The depending side plates 2 are tapered in width toward one end of thedevice to correspond with the taper of the body of the spring.

This device may be applied to a spring by slipping it over the narrow orouter end thereof and then sliding it along the spring until it comes tothat part of the spring which it fits. lVhen thus adjusted in place, itwill tend, by gravity, to hold itself in place, but, in order to preventthe device from being accidentally slipped outwardly along the springand jarred or knocked oil' and thus lost, I provide the side plates 2with a pair of outwardly-extending eyes 9 through which a wire may bepassed to tie the device to the spring, if desired.

I have shown the device applied to an upwardly bowed spring, in whichcase gravity will tend to hold the device in place, as stated, but whenit is applied to a down wardly bowed spring, the device will be solocated as to be held against slipping down toward the narrow endthereof by the usual rebound clip. Instead of applying the device to thespring by slipping it over the narrow end of the spring and sliding italong the spring, it will be obvious that the side plates may be sprungapart sufficiently to vapply the device to the spring at the point whereit is intended to lit the same. It will be obvious also, as shown inFig. 4, that the device may be applied to the spring so as to cause thepad to press against the side edges of the leaves of the spring.

The scope and nature of the invention having been thus indicated and itspreferred embodiment having been specifically described, what is claimedas new is:

l. In an oiler of the type set forth, a clip adapted to extend overthree sides of the spring and provided with an oil absorbing anddelivering pad in its one side, said pad being provided with a recess toserve as an oil container the lower extended edges of the side plates ofthe clip being provided with inwardly turned flanges engaging theopposite side of the spring from said pad whereby it is held in positionon said spring, said pad being adapted to rest against one side of thespring and a wire secured around said clip and said spring as anadditional support for said clip.

2. In an oiler of the type set forth, a clip adapted to extend overthree sides of the spring and provided with en voil absorbing said padbeing adapted to rest against one Aend delnrering pad in its one sidesaid pad side of the spring. 10 being provided with a recess to serve asan In testimony Whereofl hereunto .eix my oil Container the lowerextended edges of signature.
